Referring nowparticularly to Figs. 1 to '7, 15 represents a'building wall having a door opening l6 therein and a door I! hinged as indicated at 18 to the side of the door opening I6 and adapted, when closed to fill the door opening It. On the outer side of the building wall l5 is a porch lamp [9. On the inner side of the wall ['5 and on the ceiling of the vestibule, is a light 2|. On the door I! is a lock device 22 having a knob 23 lying on the inner side of the door, a key hole plate 24 lying on the outer side of the door and adapted to receive a key 25. A latch bolt 26 is slidable out of the end of the lock device for 00:- operationwith a switch control device 21 for the outside and inside lights l9 and 2|. The switch control device has operating control handles 28 and 29 which can be operated as the person leaves the household whereby to select the lights which are to be used. Cooperating with the switch control device is a bell ringing, push button 3! adapted when pressed to bridge contacts 32 and 33 and through its extension 34 serving to throw a thermal control bimetallic element "35 to an over-center position on contact with the stationary contact 36 in the manner as shown in Fig. 4. Current will traverse the bimetallic element 35 and when it is sufliciently heated it will be returned to its out of contact position shown in Fig. 5.

The knob 23 of the lock device is fixed to an operating member 3l that is rotatable in an annular body member 38 and which carries short elements 39 that are depressible by the key 25 in order to release spring biased elements M from the operating member 31 and lying in the annular body 38. The elements 4| are urged toward the operating member 3'! by springs 42. A ball detent 43 normally holds the operating member 31 in engagement with the annular body 38, but is releasable as the key 25 is turned so as to permit the operating member 31 to turn relative to the annular body 38 so that its gear teeth M acting upon a rack portion 45 of the latch bolt 26 whereby to retract the latch" bolt 26 from an opening 46 in the switch control device 21.

Referring now particul'arly to the wiring diagram shown in Fig. 4, the Selector switch 29 has three position including contacts. In the position l both lights [9 and .21 are kept off, and the device isleft incapacitated. On movement of the operating member 29' to position .2, the lock bolt 26 will automatically operate .upon the door being opened and. the lock bolt released from the opening 45 in the switch control device whereby both lights will be automatically operated. With the operating member 29' in the position 3 as shown in Fig. 4, both lights will be kept on regardless of theposition .of the lock bolt. As .operating memberill :of switch .28 is turned to position 4 only theceiling lamp 2| is lighted when l the lock bolt is released from. the switch control device. With the operating element in theposition 5, as shown in Fig. 5, boththe ceiling light and the wall, or aporch, light will be turned .on as the lock bolt is released from the switch control device. With the memberZB' in the position 6 the porch light only-will light up.

The switch control device is connected to an electric source a indicated by terminals 15 and E6. The wire ll leads from terminal 15 and is connected to a terminal 18 on terminal block 13.

The bimetallic element 35 is no longer in the circuit when the operating member-29 is in position 3.

Referring particularly to Figs. l and 5., contact 32 of the push button device 3! will receive current when the contacts 32 and 33 are bridged by means of a wire H5 so that current'will flow of notches .81, 82 and 83 which are engaged by a bolt 26 will have been released, compression spring 59 and slide 51 will have moved the bimetallic element '35 over center for contact with the contact terminal 36. This same result may to contact 33, wire H5, bell buzzer Ill, wirellil to wire 96, fuse 9i and terminal 16.

A cable H8 has wires l2l which extend to the parts within the svitch control device 2? and also extend through the building wall to the lamp devices I9 and 2! and the electric source. Other cables I22 and 23 lead respective from switches 29. I

These cables I22 and I23 have respectively wires indicated generally at l 22' and I23, Fig. 5. and are the several wires that connect with the respective switches in the manner shown in Fig. 4.

Referring now particularly to the form of the invention shown in Figs. 8 to 11, according to this form of the invention the lock device indicated generally at I25 is fixed to a door I26 in the manner shown in Fig. 8 and is made secure thereto by screws I21 A bolt I28 is slidable ment 36'. the bowed contact element is shown in the downwardly bowed position and in contact with the ratchet portion I54, is a magnetic core I56. ,solenoid coil I51 is provided for receiving the from the lock device I25. The handle knob I29 is accessible from the other side of the door so as to rotate operating member I3 I. On the other side of the door there is a plate I32 having a key opening for key I33 which will engage with small slide elements I34 in the manner above described. The elements I34 serve to depress the elements I35 against the action of their springs I36 so as to free the operating member I3I and in order that it can be turned by its knob I29.

Slide members I31 opposing the slides I35 are similarly arranged in annular body member I38 to permit the key removal after a half turn of the operating member I3I by the key I33. The

bolt I28 has a rack formation I4I that is engaged by a large gear I42. This large gear has a ball detent I43 serving to normally hold the operating member I3I against turning movement'relative to the annular member I38.

This lock device I25 through its bolt I28 cooperates with the switch control device above described. Fixed to the operating member I3I is a disc I45 having an indication I46 thereon which 'can be observed through a window I41. If it is desired to maintain the lights in an on position after the door is unlocked, the knob I29 is so turned that the half locked indication appears in the window I41.

The latch bolt I28 will assume the position shown in Fig. 11 and slide 51' will be lowered under the action of spring 59' to bring spring contact I30 into contact with the contact ele- The lights will remain on. While contact element 36, it will be understood that when the latch I28 is moved under the slide 51' that the load contact spring I30 will be elevated to assume an upwardly bowed position.

The upward movement of the slide will be against 1;

the action of the coil spring 59'.

The operating member I3I has an insulated disc I 48 with a metal conductor insert in the periphery thereof, as indicated at I49, Fig. 10.

Two spring contact fingers I5I and I52 may engage this insert I49 when the operating member is in the half locked position.

On the operating member I3I is a ratchet gear I53 which is operated by a pawl arm I54 on a U- On-the lower leg of the shaped member I55. member I55 and running parallel with the A core I56 and when energized the core will be drawn toward the coil and the ratchet pawlarm I54 will rotate the ratchet gear I53 and turn the operating member I3I so that the bolt I20 by the action of the gear I42, idler gear I42, will cause gear rack teeth MI and the bolt I26 to be moved. fully locked position. The idler gear I42 is journalled on a pin I40 that is supported on an upwardly extending portion I40 of the casing.

Electric source terminals I58 and I59 supply current to the coil I51 when the contact fingers The bolt I28 will be moved to its ment I62 will start to be heated by the current passing through the same and after a time the bimetallic element I62 will bend to assume the dotted line position indicated at I65. A contact I66 which is insulated by an insulating member I61 from the bimetallic-parts will be carried to a contact I68 so that immediately coil I51 will be energized and the core I56 will be pulled through the coil I51 and the ratchet portion I54 will have acted upon ratchet plate I53 to turn operating member I3I and the bolt I28 to its fully locked position.

The bolt I28 will elevate the slide 51 to cause the bowed contact I30 to be lifted from contact 36. The light circuit which is controlled by the switch control device 21 will thereby be broken. I i

All of the parts of the lock device shown in Figs. 8 to 11 are contained in a housing I69 which is attached to a plate I10 by screws Hi. The plate I10 is in turn secured to the door by long wood screws I21.
